RE: discovery vs. discovery
Hello, .21
Some comments,
What is the 'network node' in 2), is it an AP, the mobile station or
something else? I mean that it is a bit difficult to follow what the
sentence "a mechanism definition or protocol specification for a network
node to locate .21 aware nodes which are producing "neighborhood
information" in .21 format" means exactly.
The, regarding the offline comments about 3GPP/PP2 willingness/ability to
modify their L2 - this is a question to be handled officially and in a
professional way in the liaison activity. As we have seen in the 3GPP TS
23.234 the intention is to use SIM/USIM based authentication and 3GPP AAA
server for WLAN users in order to be able to interwork with 3GPP system. In
order to enable the seamless handover between the above mentioned systems,
it should be clarified which of the existing 3GPP TS'es need to be updated,
and if there is needed new ones, the same is valid for 3GPP2. Also what is
needed is a realistic timeplan for the needed updates to be done, and who
are the contact persons for each TS.

PS. A good book to read about the 3GPP radio access is 'Holma & Toskala:
WCDMA for UMTS', maybe you Michael have a copy since they are your
colleagues from Nokia...

Subject: discovery vs. discovery
Hi everyone,
In section 2, Functional Requirements, a suggestion was made to call the two
types of discovery under discussion:
1) Network Discovery
2) Informational Discovery
Here is a potential framework for the two.
1) Is the "traditional" network discovery concept/requirement. .21 would
provide a media independent specification that defines optimal ways to
determine the existence of L2 networks. Most wireless networks offer the
beacon/probe type advertisement now. .21 might specify the essential
information that is required across all conformant MACs within this
function.
2) Informational Discovery would be a mechanism definition or protocol
specification for a network node to locate .21 aware nodes which are
producing "neighborhood information" in .21 format. Some MACs offer such
information now. We have discussed a variety of additional information
beyond that defined in any MAC, as potentially being useful in optimized
handover. .21 might specify a way of advertising additional information in
an extensible way that permits the "handover state machine" to access it.
It might be that the two services compliment each other, so for MACs which
don't have a beacon (e.g. .3) or can't/don't want to modify the beacon, they
could publish the 1) through a 2) service.
Please comment!
There are some strong comments offline that 3GPP/PP2 can not modify their L2
to add functionality such as the above. Are there comments on this too?
Best Regards,
Michael
